15 steps
  1. Removing the back cover

    1. Insert the spudger into the gap next to the headphones. There are 16 clips on the outside under the back cover. You have to disconnect them by moving the spudger around the entire smartphone one time. Alternatively, you can detach the back cover using your fingernails.
    2. Then you can take off the back cover.
  2. Removing the battery

    1. If your Samsung Galaxy’s still on, turn it off by holding down the standby button for about three seconds and following the prompt on the display.
    2. Now use the spudger or your fingertip to lift the battery (see figure 1) and then remove it (see figure 2).
  3. Removing the SIM card

    1. Use the spudger or your finger to push the SIM card all the way into the slot (see figure 1). After a gentle click, the SIM card will come out (see figure 2).
    2. Now you can pull it out with your fingers.
    3. Repeat this process if you’ve installed a microSD card.
  4. Removing the plastic cover

    1. Remove the 9 Phillips screws that hold the plastic cover in place (see figure 1).
      9 x 4.0 mm Phillips screws
    2. Lift the cover and the chrome frame to remove them. The cover is attached to the display at 14 points. Insert the spudger between the chrome frame and the display. Start at the level of the Home button (see figure 2) and move the spudger once around the entire phone to detach all connections (see figures 3 and 4). Then you can remove the midframe.
  5. Disconnecting the connectors

    1. Now you can disconnect the following six connectors. Be very careful (see figure 1).
      LCD/touchscreen
      USB connector
      Front camera
      Earpiece
      Antenna cable
      Headphone output
      Make sure you don’t break off the resistors that are soldered onto the logic board.
    2. Place the pointed tip of the spudger very slightly below the contact and carefully lift it up. The pictures show where you should put the spudger to avoid breaking off the little resistors even if it slips (see figures 2 to 5).
  6. Removing the logic board

    1. Remove the screw holding the logic board in place (see figure 1).
      1 x 3.0 mm Phillips screw
    2. Now you can carefully lift the logic board using the spudger (see figure 2) and remove it by hand (see figure 3). The rear camera sometimes sticks a little bit. Be careful.
  7. Removing the vibration motor

    1. Now remove the vibration motor. Carefully insert the pointed tip of the laboratory spatula or spudger below the cable set (see figure 1) and work your way toward the motor. It’s sometimes glued firmly in place. If you still can’t detach the vibration motor, you can use a heat gun to warm it slightly and soften the glue.
    2. Now remove the vibration motor (see figure 2).
  8. Installing the vibration motor

    1. Now put the vibration motor back in the appropriate position (see figures 1 and 2).
    2. The old glue is usually enough to hold it. Press it on firmly. If the vibration motor is too loose, use new glue. If the motor isn’t attached securely enough, your phone’s vibration will be weaker.
  9. Installing the logic board

    1. Now put the logic board back in the frame. Start with the rear camera connected to the logic board. Once it’s fitted correctly, you can install the rest of the logic board (see figure 1).
    2. Make sure the cables don’t get under the logic board.
    3. Use the picture to check whether your logic board is positioned correctly (see figure 2).
    4. Now fasten the screw for the logic board (see figure 3).
      1 x 3.0 mm Phillips screw
  10. Connecting the connections

    1. Now put the following five connectors back in the corresponding slots. Use your finger to carefully press them into place. Only use as much pressure as you need for the contacts to gently click into place.
      LCD/touchscreen
      USB connector
      Front camera
      Earpiece
      Headphone output
      Antenna cable
